What was the code? lean mixture? If so make sure there is no leak in the exhaust. I have worked on a lexus suv, but it was an 89. It had a lean mixture code. After examination I noticed a exhaust leak which was not apparent at first, there is a section in the exhaust the is very thin, and prone to leakage, causing the lean mixture code.

You own a high end luxury vehicle as do I, 2005 ES330, the dealership is the best place to get Lexus problems fixed. With my own vehicle, I had a thermostat fault code come up, and like you it would reset itself and come back. The code said it was the thermostat and I queried it with my tyre guy. He also said it is a thermostat code. I said but it isn't overheating. He told me that the computers in Lexus are so clever they are actually looking for the water to reach x degrees in x minutes. He replaced the thermostat, the fault never came back. Anyway back to your P0172 Error code.

https://www.autocodes.com/p0172_lexus.html

Possible causes
Faulty front heated oxygen sensor
Ignition misfiring
Faulty fuel injectors
Exhaust gas leaks
Incorrect fuel pressure
Faulty Mass Air Flow (MAF) sensor

The first thing I would try is that stuff that you add to your fuel to clean the injectors.

Engine manage light came on my lexus is200 and engine sounded like it was miss firing, then the trc off light was repeatedly flashing is the a orob with the brain


Get yourself an On board display scanner from ebay about 20GBP.

read the instructions. Plug in to the under dash socket and note the fault code. Look up the code and then see if you can fix the problem. If you can't, clear the engine management light [the next time you start it the light will come on again] and take it to a garage Don't tell them what you know, see if they feed you with a lot of rubbish and try to rip ou off.

Air sensor check engine light


Ok as a guess that you have a SUV and you have different air faults. if you are a DYI'er go to an auto parts store and get an error code tool. Harbor freight for $30-50. Hook it to the car and find out which sensor is it calling for. Note, you can reset the check engine light on most tools that are not the cheapest.
P1130
Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1)

P1133
Air/Fuel Ratio Sensor Circuit Response Malfunction (Bank 1 Sensor 1)

P1135
Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

P1150

My Check Engine light came on, code reads bad O2 Sensor heat element Bank One Sensor One, This car have 2 front and 2 back O2 Senors, Is Bank one Sensor one on the Driver side or passenger side ? Thank...


bank 1 is the side cylinder 1 is on.sensor 1 is the first sensor in the exhaust on that bank from the manifold.cylinder 1 is the most forward cylinder on the motor when you look across the motor at the front of it to see which head/vlave cover is farthest forward.

Need to remove oxygen sensor in bank 2 for lexus rx 300 where is it and how to removed


Bank 2 reffers to exhaust manifold where the # 2 cylinder lies. Depending on how many sensors you have on that side you will find the sensors there. The sensor clossets to the engine would be sensor 1 bank 2 and if you have another on bank 2 it be reffered as sensor 2 bank 2. The same applies for bank 1 sensors the one cossets to the engine is rtefferred to sensor 1 bank 1 and sensor 2 bank 1. Hope this helps.

The engine light and VSC light are on (Vehicle Singapore 2004 Lexus RX 300. Diagnostics report Error code P0037


your o2 sensor is bad. vsc will go on for any small DTC displayed on the MIL (cel)

P0037 LEXUS P0037 LEXUS - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 2 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
Possible causes - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) When is the code detected? The P0037 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit P0037 LEXUS Description Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECMcontrols the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

Bank 2 is on the passenger side. Bank 1 is the driver side. Sensor 1 is before catalytic converter. Sensor 2 is after catalytic converter. You can get Bosch part at Autozone for half of the OEM part price. I recommend to buy this first so you know that it looks like and how the connector is mated. There are two wrenches they sell for this job. The socket one works better but requires 1/2" drive. You need to jack the car up as high as you can and use a headlamp so you can see better. Loosen the screws (about 6) to remove the cover so you can see sensor 1 (sensor 2 is visible by looking at the exhaust system). Open the sensor first and then use a flat head screwdriver to pry open the mating connector while pulling the sensor down (side of sensor connector that has a ramp is the side you need to pry). Once old sensor is out, you can replace with new sensor. Remember to disconnect the ground cable on the battery and reconnect it to reset the check engine light before you start the engine. Good luck!
